Huffman coding and decoding using Android

摘要

Code compression technique is used for the reduction of codes to allow transportation of digital data from the transmitter (source) to the receiver (destination). These fixed length codes are converted into variable length codes having varied number of bits. The Huffman coding technique is found to be an optimal solution of transportation of data. It generally follows the Lossless Compression technique where symbols in encoded data are converted into a binary symbol and this precomputed text availed is further divided into blocks having variable lengths and condensed under efficient algorithm encoding procedure using code words having limited value. To increase the compression ratio these code words could be reused for encoding different compatible blocks. An Android app is been created to portray this technique for the ease understanding.
